o9k-init

o9k-init is a skill for Claude Code from Bumblebiber/its-over-9k. It costs 80 tokens per session (5,912 once invoked), scanned C, original, MIT.

A guided setup tool for o9k, a collection of companion components for coding agents. It checks what is installed, asks which parts you want, resolves conflicts, and applies the setup.

In plain words
What is it for?
Use it for a first installation, reconfiguration, or extension of an o9k setup, including after an update adds a new component.
Why use it?
It removes the need to manually inspect installations, choose compatible components, and handle conflicting files.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions subagents; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

o9k-init scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

How it starts

The opening of the file, as written. The whole thing — 459 lines — stays where its author put it; the contents beside it link to each section on GitHub.

o9k-init — Guided Setup

The one flow that takes a machine from "just added the marketplace" to a conflict-free stack of exactly the pieces this user wants. It detects before it asks, asks before it acts, and never destroys data. /o9k-guide explains a setup; /o9k-init builds one. After /o9k-update reports a NEW PILLAR, re-run this flow to offer it — --refresh-hosts alone only syncs pillars that are already installed.

Complete is not the goal. o9k connects frameworks; it does not sell all of them. o9k-core is the connector and installs unasked. Everything else — the four other pillars and the five spun-out packages — is a separate opt-in with a default of no. A user who only wants core plus scout has a correct install, not a partial one.

Step 0 — model check (do this before anything else)

Setup is detection + questions + installs — a cheap-model job. Check which model you are:

  • Flagship active (Claude Opus/Fable, or another vendor's top model): recommend once — "Setup doesn't need a flagship. Switch with /model haiku and run /o9k-init again — same result, fraction of the cost." If the user declines or just keeps going, continue — don't nag twice.
  • Either way: keep the main context for the interview and decisions. Push the heavy lifting — broad detection sweeps, install execution, install verification — into cheap subagents (Haiku-class) whenever the harness supports it.

Step 1 — detect

node "${CLAUDE_PLUGIN_ROOT}/scripts/o9k-init.mjs"

Read-only, instant. The first line is a Platform note — surface it to the user before the interview when it lists limitations (team-up needs tmux; native Windows needs WSL for it). Never offer something the OS can't run — skip the team-up question on native Windows and say why.

The snapshot also gives you: pillars (each with its for: / not for: line), git, memory backend, companions, a Spun out of o9k section, bundle deltas (what each bundle would still add), rival frameworks, open arbitrations, a Hosts section, and an Unknown installed section (plugins / MCPs / skills present on the machine that are not in compat/registry.json). Detection is best-effort — "no" means not detected, so if the user says they have a tool, believe them.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

o9k-init is a skill published in the GitHub repository Bumblebiber/its-over-9k (0 stars, last pushed 10d ago), licensed MIT. It adds 80 tokens to every session and 5,912 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (strips warnings and disclaimers, asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
